Doug Keenan has posted a note at the bottom of the notice about his £100,000 challenge, indicating that he has reissued the 1000 data series. This was apparently because it was pointed out to him that the challenge could be "gamed" by hacking the (pseudo)random number generator he had used.
Brandon Shollenberger emails to say that this is a terrible thing, but I can't get terribly excited about it. Presumably it doesn't make any difference to those who think they can detect the difference between trending and non-trending series.
